DPIP (Standard dbx Input Module)JBL DrivePacks are equipped with a modular input bay and are available in severalversions. The standard DPIP input module features analog audio inputs andsophisticated onboard digital signal processing technology. Precision bandpasslimiting, pre-equalization filters and automatic self-test functions ensure optimizedperformance. Front panel controls include a 32-position detented rotary attenuatorcalibrated in 0.5 dB steps which provides a 16 dB range of control. This can beuseful for setting up downfill shading or overall system gain structuring. Anotherfeature is the “Enable Subwoofer Filter” button. This is a momentary-contact typeswitch which enables or disables the selected function. On subwoofer applications,the low-pass frequency is set to 80 Hz. For full-range systems used with subwoofers,the high-pass is raised to 80 Hz.
DPAN (Optional HiQnet Network Input Module with Analog Audio)In addition to all of the features included on the standard input module, the DPANadds 100 Mb Ethernet networking functionality and HiQnet™ compatability. It enablesremote control and monitoring via HiQnet System Architect™ software. NetworkControl and Monitoring is enabled by the DrivePack Software Device Panel suppliedwithin HiQnet System Architect. Network capabilities include monitoring of status,input and output levels, clipping, temperature, load faults and gain reduction.Additional control features available in software include load supervision, dynamicprocessing, ten internal pre-e.q.filter presets, delays, onboard noise and sine-wavegenerators, network device event logging, and user alert messaging.
DPCN (Optional HiQnet Network Input Module with Digital Audio)In addition to all of the features included on the DPAN, the DPCN input module addsCobraNet™ to the mix and offers the ability to direct up to 64 audio channels on onenetwork, with digital audio and remote control and monitoring via Ethernet combinedon a single cable. DPCN includes the option to use an analog input as a backupaudio source providing you complete reliability and flexibility to cover any situation.With HiQnet System Architect providing the software user interface, the HiQnetcommunications protocol provides remote access to digital speaker preset files in theJBL DrivePack. As with the DPAN, user-addressable features include ten internal pre-e.q. filter presets, up to 2 seconds of delay per channel, onboard noise and sine-wavegenerators, network device event logging, and user alert messaging.
JBL DrivePack® input modules are used to implement crossovers, equalization, time alignment, andprotection for the attached speaker system. Speaker-dependent settings are not user-configurablefrom any version of the input module. The following options are available for connectivity, audiosignal path and control functionality.

VT4887ADP Acoustical MeasurementsThe frequency response measurement shows individual
bandpass responses with composite response overlay. TheVertical Beamwidth results range from a single box up to an 8-box array with 10° splay angles between adjacent array elements.
All measurements provided herewith are derived from datagathered with a calibrated measurement microphone centeredon-axis of the box or array, with polar data points taken symmetrically around the measurement axis.
All polars were taken as groundplane measurements at adistance of 10 meters, with data gathered on 5-degree intervalsfrom 0-355° using the MLSSA measurement system.

VERTEC System ArraysThe VT4887ADP is an articulating line array element designed for use in
vertically oriented, multi-box systems. A nominal horizontal coveragepattern of 100° is maintained, while setting the individual box anglesallows the creation of arrays with varying vertical coverage angles. Verticalcoverage of an array is a function of the number of boxes used and thesplay angles chosen.
VT4887ADP enclosures can be suspended from available VT4887-AF orVT4887-SF array frames. Due to the use of JBL’s S.A.F.E. suspensionhardware system, rigid arrays can be constructed that can be tilted eitherupwards or downwards at radical angles. Front hinge bars are tightlycoupled, while rear hinge bars are used to set angles from zero to tendegrees for adjacent enclosures.
VT4887-AF (Array Frame)This array suspension frame is crafted of 6061 heat-treated aluminum. It
includes 11 (eleven) attachment holes for shackles, each fitted with bronzebushings for long life. These holes are set on approx. 4" centers. Eachhole has an I.D. (inner diameter) of 25.4 mm (1 in). Array frames arefitted with SAE Grade 8 bolts, 7075 Grade aluminum receiver blocks andsteel quick release pins with stainless steel restraining lanyards. Weight:36 kg (80 lb).
VT4887-SF (Short Frame)This array suspension frame is crafted in similar fashion to the VT4887-
AF. The VT4887-SF is primarily intended for use with smaller clusters in tight spaces or distributed satellite arrays. Optional anchor for use on bottom of large arrays. Weight: 18 kg (40 lb).
VT4887ADP-ACCThe VT4887ADP-ACC includes items necessary for the proper transport
and protection of the VT4887adp. This accessory kit includes: (1) VT4887-DOLLY & (1) VT4887ADP-COVER.
The JBL DrivePack® DP2 attaches to the backpanel of the enclosure, creating the modelVT4887ADP. Robust Crown amplification andonboard digital signal processing are combinedto create a compact powerful, integrated audiosystem.
Important Note: The VT4887ADP-ACC issold as a separate item. One kit should beordered with each VT4887 to ensure safeand reliable transport of each system inportable use.
